So I've got a $3000 budget to upgrade from my 2007 15" MBP. I was set on a rMBP but after seeing so much talk about lag issues, the integrated graphics not being up to snuff, and ten the whole not much stuff has caught up to Retina I'm thinking I may be better off with a MBA. I'm your average college student so the higher portability of the Air is a huge plus. The main thing in concerned with is if it will be enough for Aperture and occasionally Final Cut Pro with the i7 and HD4000 graphics. Also plan on setting up a XP bootcamp partition for the few programs I use that aren't Mac compatible and for League of Legends. Should I just get a rMBP and hope that any of the lag issues can be fixed via software or get a 13" MBA and use the money I'd save to put toward a next gen rMBP or even an iMac?
